WINDOW SCREEN.

My invention relates to window screens of the extensible and collapsible type, and my purpose, generally speaking, is to provide a screen, specifically a full length screen, which may be extended and collapsed both in length and width, whereby it may be adjusted to iit windows of various diiierent sizes.

A window screen constructed in accordance with my invention is composed essentially of four sections, two upper and two lower, or, in other words, an upper and lower left hand pair and an upper and lower right hand pair, the sections of each pair being slidably connected together so as to be extensible and collapsible with respect to one another, and the two pairs being suitably connected together so as to be relatively extensible and collapsible in a direction at right angles to the direction in which the sections of the respective pairs are extensible and collapsible, whereby, as aforesaid, the screen is adjustable both4 in length and width so as to fit windows of various dierent sizes.

In a screen constructed as stated it is desirable that all of the sections be so connected together as to avoid the possibility of the sections bulging or springing with respect to one another in such manner as topermit spaces to exist between them through which iiies or other insects might pass, and accordingly it is my more specic purpose to so connect or interlock the sections that the possibility of saine bulging, springinoor spreading apart in such manner as to iorm openings which would permit insects to pass through the screen is entirely avoided.

It also is my purpose to provide means of an exceptionally simple, reliable and efiicient nature to detachably secure a screen within a window.

Furthermore, it is my purpose to provide an extensible and collapsible screen ofthe type mentioned which is of simple, inexperisive construction, strong, durable, easy to adjust, and which is efficient in use.

With the foregoing and other purposes in view, my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanaying drawings and defined in the appended claims.

in the drawings, wherein like characters of reference denote corersponding parts in the diferent views :m i

Fig. 1 is a front elevation of an extensible Iand collapsible screen embodying the novel and essential features of my invention;

Fig. 2, a section on an enlarged scale taken approximately on the line 2-2 of Fig. 1;

Fig. 3, a section on an enlarged scale taken approximately on the line 3-3 of Fig. 1;

Fig. 4L, a perspective view showing the four sections of my screen separated from one another; and

Fig. 5, a detail perspective View showing my improved means for fastening a screen within a window.

By reference to the drawings it will be observed that my improved screen is composed essentially of four screen sections, A, B, G and D, each consisting of a rectangular frame composed of an upper rail 10, a lower rail 12, an inner side rail 1a and an outer side rail 16, said rails preferably being formed from sheet metal bent into U-shape in cross section and having the marginal portions of the respective screen elements 18 clamped therein.

The side rails 1li, 16 of section A, the upper left hand sectionas shown in the draw ings, have pressed therein or are otherwise suitably provided with outwardly directed, longitudinally extending dove-tailed grooves 20, 20, respectively, which slidably receive inwardly directed, longitiulinally extending tongues 22, 22, pressed from or otherwise suitably provided on the side rails 14, 16 of section B, the lower left hand section as shown in the drawings, whereby said sections A andA B are connected together for relative collapsible and extensible adjustments.

The side rails 14, 16 of section C, the upper right hand section as shown inthe drawings, have pressed therein or are otherwise suitably provided with outwardly directed, longitudinally extending dove-tailed grooves 24, 24, respectively, which slidably receive outwardly directed, longitudinally extending tongues 26, 26, respectively, pressed from or otherwise suitably provided on the side rails 1st, 16 of section l), the lower right hand section as shown in the drawings, whereby these sections are connected together for relative collapsible and extensible adjustments in the same directionas the sections A and B.

The upper rail 10 of one of the upper sections, specifically section C in the embodiment of my invention illustrated, is turned upon itself to provide, or is otherwise suitably provided with, a groove 28 which slidably receives the upper marginal edge portion of the upper rail of the other upper section, in this particular instance section A, while, in like manner, the lower rail 12 of one of the lower sections, in this instance section D. is turned upon itself to provide, or is otherwise suitably provided with, a groove 80 which slidably receives the lower marginal edge portion of the lower rail of the other lower section, specifically section B, thel pair of sections A, B overlapping the pair of sections C', D, whereby, as is apparent, the pair of sections A, B, are slidably connected with the pair of sections C, Dv for relative' collapsible and eXtensible adjustments in a direction at right angles to the direction in which the sections of the respective pairs are adjustable with respect to one another. ln other words, assuming that the tongue and groove connection between the sections A, B and C, D provides for extension and collapse of the respective sections in a vertical direction, it is manifest that the sliding connections just described between the sections A, C and B, D provide for extension and collapse of the right and left hand pairs of sections with respect to each other in a lateral direction.

ln order to interlock or so connect the left hand pair ofsections A, B with the right hand pair of sections C, D as to prevent the sections of either pairl from bulging or springing outward with respect to the sections of the other pair in such manner as might' result in openings being produced between the respective pairs of sections through which flies or other insects might pass, I turn the upper rail 10 of one ofthe lower sections, in this instance section D, upon itself toy provide, or otherwise suitably provide same with, a groove 32 which slidably receives the upper marginal edge portion of the upper rail 10 of the other lower section,`

specitically section B, the result being as aforesaid that the right and left hand pairs of sections are interlocked between the upper and lower ends of the screen considered in its ventirety so that neither pair of sections cany spring or bulge outwardly with respect to the other pair of sections.

By extending the tongues and grooves of both the right and left hand pairs of sections outwardly l am enabled to provide a sectional screen in which the respective pairs of sections lie closely adjacent to one another in overlapped relation, the only space existing` between the respective pairs of sections being the slight space necessary to accommodate the overturned portion of the upper rail l0 ofA section B which provides the groove 32. Thus it is apparent that I have provided a screen which is adjustable both in length and width, in either direction irrespective of its adjustment in the other direction, and in which the respective sect/ions in any adjustment thereof are so interlocked as to prevent them from spreading apart in any manner which would produce an opening or openings through which insects might pass.

As asimple, inexpensive, easily applied and easily manipulated means of detachably securing my improved sci-cui in a window frame l provide the means illustrated in detail in Fig. 5 of the drawings, sa ie consisting essentially' of a screw eye 31- and a pin 3G, the former being adapted to be fastened into the window frame and having the opening in its eye of elongated shape, and the latter bei-ng provided at one end with a head 88 and at its other endwith a lateral extension or extensions 40. it screen adapted to be secu d in place by said screw eye and pin is provided in a rail thereof with an opening a2 sutiiciently large to admit the extension or extensions et() of pin 36, but small enough to prevent the head of said pin from passing therethrough. The opening 42 is alined with* the opening in the screw-eyel and the pin is passed through sai-d opening i2 and the opening in said screw eye and then is rotated a quarter turn, the result being that the head of the pin engages the outer face of the screen rail and the lateral extension of the pin engages the rearV face of the screw eye thus detachably securing the screen to the window frame. Obviously, as many such securing devices as desired may be provided for any particular screen.

From the foregoing description considered in connection with the accompanying drawings it is believed the construction, operation and advantages of my improved collapsible and extensible screen will be fully understood. I desire to point out, however, that various changes and desirable additions may be made in andto the structure shown within the spirit and scope of my invention as defined in the appended claims.

I claim:

l. In combination with a window screen including a frame having an opening therethrough, a screw eye adapted to be secured to a window frame, and a pin provided at one end with a head and at its other end with a lateral extension adaptedto be passed through the opening in said frame and through said screen eye and rotated to secure the frame to said screw eye.
